It is narrated from Sayyiduna Ibn Amr (may Allah be pleased with him) that one day the Noble Prophet (peace and blessings be upon him), while mentioning prayer, said: "Whoever observes it regularly, it will be a light, a proof, and a means of salvation for him on the Day of Resurrection. And whoever does not observe prayer regularly, it will not be a light, a proof, or a means of salvation for him, and on the Day of Resurrection, he will be with Qarun, Pharaoh, Haman, and Ubayy ibn Khalaf."
